WATER SILENCER Filed Nov. 15, 1933 .Z A llllllll i an I l 7/ 9* a lillli Patented Get. 9, 1934 UNITED STATES PATENT GFFEQE 1 Claim.

This invention aims to provide a simple device, adapted to be interposed in a pipe through which water or other liquid flows, with a view to avoiding knocking, vibrating and noise. The invention is 5. shown as used in combination with a flush tank,

but it is not confined, in use, to that purpose.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may bemade within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawing: Fig. 1 shows in longitudinal section, a device constructed in accordance with the invention, as-

sembled with an intake pipe, and with an article whereinto the intake pipe discharges;

Fig. 2 is a transverse section of the device per se. The device may be made of metal throughout. It comprises a cylindrical casing 1, including a body 2. A first head 3 is secured in one end of the body 2, and in the opposite end of the body 2, a

30 second head 4 is secured. Disposed within the body 2 is an axial tube 5 secured in the heads 1 and 2, and extended outwardly beyond the said heads. Within the body 2, the axial tube 5 has oppositely disposed longitudinal slots 6.

Transverse baffle plates '7, which may be in the form of circular disks, are disposed in the body 2 and are spaced apart transversely, the bafile plates I being secured to the tube 5, between the ends of the longitudinal slots 6. The bafile plates 7 40 have openings 8, arranged in a circle about the tube 5, the openings 8 of the several baflie plates being out of alignment, as Fig. 2 will show. The baffle plates 7 may be connected at their peripheries by any desired number of rigid tie rods 9.

The device is capable of use under a wide variety of circumstances. By way of example, therefore, but not of necessity, one end of the tube 5 is connected at 10 to a water intake pipe 11, adjacent to the second head a. Adjacent to the first head 3, the end of the tube 5 is connected at 12 to the inlet 14 of a flush tank 15.

In practical operation, the water enters by way of the pipe 11, and traverses the tube 5. Some of the water passes out of the tube 5, through the longitudinal slots 6 in the tube, and passes through the non-aligning openings 8 of the baffie plates 7. Ultimately, this water again enters the tube 5, adjacent to the first head 3, and passes on its way to the flush tank 15 or other structure wherewith the device is employed. The structure is simple in operation, but it will 75 be found thoroughly eflicient to check the flow of water sufficiently to break up all vibration and to dispose of noises which are common when water flows into a flush tank or into any other structure.

Having thus described the invention, what is claimed is:

In .a water silencer, a cylindrical casing made up of a body and heads assembled with the ends of the body, an axial tube extended through the heads, and transversely spaced, approximately parallel baffle plates mounted on the tube and located within the body, the baffle plates being supplied with openings arranged about the tube and disposed out of registration in the several baiiie plates, the tube being provided with con tinuous longitudinal slots extended toward the heads, beyond those of the baffle plates which are adjacent to the heads.
